Abstract: The classical Particle Swarm Optimization (PSO) neglects the difference among particles while updating a particle's velocity in a generation. I}o cope with this issue, a novel Distanccbased Adaptive Fuzzy Particle Swarm Optimization (DAFPSO) was proposed in this paper. The DAFPSO designed membership functions to tune the basic parameters used in updating a particle's velocity according to the distance between the current particle and the global best particle. Several classical benchmark functions were used to evaluate the (DAFPSO.The experiments demonstrate the efficiency and effectiveness of the proposed DAFPSO.
